Marine Engine Exhaust Design - Complete Catamaran Build Ep268

Marine Engine Exhaust Design is not a simple matter as there is so much to take into consideration such as water level, raw water mixing height and Exhaust muffler and siphoning issues. An extra $3000Aussie dollars to sort this one but, beware , everything to do with Marine Engines is super expensive.

Its been a long time since you posted that first clip and it looks like you are going to prove any naysayers wrong including me. good job

[@saulzain1957]

Won't be long before ya'll be sipping margaritas in the middle of the oceans! 🎉

[@redpillpirate111]

Zack and Ellen need a KZbin channel to chronicle their adventures around New Zealand. She can call it "but wait, there's more!" 🤣

[@lets_go_see_]

another positive sign that it is coming together! :)

[@fonhollohan2908]

BTW, Ross, Where that battery cable is going through the hole in that Battery Storage area, I wouldn't use Sikaflex or Silicone I'd use a Grommet that's what Grommet's are used for.

[@latitudeash]

Beet electrical area. Label everything and draw up a circuit diagrams. That way in 10yrs when all is forgotten you have reference book. 👍🏼.

[@normanboyes4983]

Great progress Roscoe. Wow on the new Yanmar exhaust price. There are three price levels 1. Land equipment. 2. Marine Equipment. 3. Yanmar Stuff.😳

[@andrewmaiden3738]

This Boat is going to be a thing of beauty, such detail and so well thought out. The electrics are so neat. I hope Zac is on premium pay!

[@br5498]

He’s with the daughter….there’s the exchange

[@LifeOnTheHulls]

Too funny but very true.

[@latitudeash]

Save that gasket as a spair, it’s still good and if the replacement one leeks in a remote area of the world you got one which is Basicly new

[@jimdickerson1401]

Your patience is beginning to show you have a very beautiful boat and you do absolutely gorgeous work anybody would be proud of it

[@rayboucher479]

Copper coat or anti-seize them studs and when it is time to remove them it should help .

[@nickcooper14]

Amazing how a bit of colour can make an area look finished👍🏼👍🏼👍🏼 Great work guys

[@LifeOnTheHulls]

Feels like a milestone even with a bit of colour.

[@Baddco]

Good work. Why not a small led strip in that helm hole for future convinence. You can get a gas tight gland to go around cable though bulkhead will also solve problem of chaffing.

[@aserta]

One thing i'm eagerly awaiting is when the props will spin for the first time, that's a major goal in the boat's build.

[@martinneubert4068]

Excelent work Ross and Zack Very nice viring. I sendt you a bit via paypal. Take care mate. All the best.

[@hooter7003]

If you ever decide to sell it you can ask a premium price over a lagoon 450 even used because It is built with passion

[@rayboucher479]

Bulk head fittings for the wiring and tubing that goes through the bulkheads you can drill them a little larger if they are too small and then use rubber ferrules to seal . They will not be good for pressure specs but will seal excellently and look beautiful. I have always used 316 SS or monel but I would think even plastic type would be good for this application and much cheaper. Get er done !

[@kenbaustin4533]

So glad that you got some competent help there Ross! By the time this is all done you will be walking him down the isle to give him away!

[@hagn7350]

This is going to be the manufacture reference for future boatbuilders ( I hope ) that boat is going to be a beast.

[@SpiralDiving]

I would think about a 24V system... Turn the batteries around so the cable bend is smaller?

Another step closer Ross. Just looking at the conversions and 0000 is equivalent to 120mm2 which you can obtain pretty easily in Oz for $55/m. From what I've seen the best way to join batteries to your system is to have equal length cables from each battery back to a common busbar or terminal post. This ensures all batteries are used equally if my understanding is correct. You'll probably be fine for the short-term, but it may be worthwhile considering down the road.

[@gunnarfernqvist4896]

Very nice wiring work! But what did the supplier have to say about the different colors of those exhaust mixers? Everything on this boat is so gorgeous and perfect but you accept these two to be different colors, doesn’t sound like the Ross we have learnt to know over the years?

[@secretsquirrel6308]

I highly appreciate a neat and orderly wiring installation. This is grand how tidy your electrical room is. Good job for the sweat to do it right the first time. Batteries in a box. Will you show us your venting and how you will secure the batts in place.

[@icelandviking1961]

Right on it today with an exhausting problem

[@LifeOnTheHulls]

I was going to title it, this is exhausting.

[@nez3009]

Those batteries should hold ya

[@aserta]

5:12 true, but you should borrow a torque wrench in the right range and check the major bolts. Just saying. I was talking the other day with a friend of mine who works with a big chain of heavy duty equipment distribution and their bosses basically told them to start checking engines and power trains, something he said was the first time that'd been implemented in their outfit. Won't name names, i don't want to get my friend in trouble, but we're talking about a pretty big house name in the industry, one myself i had never put to question when i'd gotten new equipment from them before. Apparently we live in an age where CEOs have cut every corner that could be cut, wound up making circles out of the production and now they've started cutting from the center, sending production line tasks to us, the purchasers. An unpleasant thing for sure if it isn't a case of a bad production line spooking my friend's bosses.

[@stephenj9563]

Good episode Ross But I thought we were going to see the lights come on. Next week?

[@LifeOnTheHulls]

Haha,Zach didn't get his stuff together,I was ready with the batteries mate.Maybe next week and good pick up.Rossco.

[@latitudeash]

Bloody expensive kit and you had to get two. Shame it was not the same colour. That would drive me mad…🤣😂

[@wandomwabbit3014]

have you the new type of propeller from Sharrow Marine with between 9 and 15% increase in efficiency expensive but sound so good

[@jimlofts5433]

power !! thru hull / wall connectors ?? used them on my 300A LiFePo4 install - different Amperages / Watts available - but too late the vlog marches on well done - watching some usa vlogs and the install regs don't seem to be universal - go figure

[@PN_48]

Another great vid mate! I had wondered with the lithium whether the purpose of the sealed box is to be able to flood them with cooling water (in the case of a battery overheating) without then flooding the boat. Otherwise, I just can’t fathom a reason for the new requirement!

[@LifeOnTheHulls]

I feel the standard has been adopted from an old lead acid and agm off gassing standard and will likely update to a more sensible outcome.Ross

[@PN_48]

@@LifeOnTheHulls That makes more sense! But yep, if Lithiums are gassing you know there’s an issue😂 Progress is looking good; I’ll bet you guys are getting excited to leave the tent and get her in the water.

[@rayboucher479]

Hope it is at least 316 SS and for that price they could have at least give you 2 shinny ones !

[@LifeOnTheHulls]

They do have an interesting finish don't they.Rossco

[@bobthesnobscotland2821]

Thank fuch he is not away yet

[@bronco351mal]

Are the risers cast iron? if so get use to replacing them every so often...... 😏

[@pierremitham2964]

I'm surprised you had to buy those seperately. My Yanmard 4JH came with that exhaust as standard...

[@vettepicking]

I hope the new riser is stainless.....i believe you can buy stainless aftermarket risers for half the price of a oem cast-iron unit....

[@rl3898]

Not with Yanmar mixed metal corrosion stuff !

[@vettepicking]

@rl3898 gaskets separate most risers. Seen plenty and made a couple new ones in ss.

[@echtogammut]

9:17, am I crazy or did you not put a gasket on the second mixing muffler? KZbin stopped alerting me to new episodes a few months back, so it looks like I have lot of episodes to catch on.

[@WillPittenger]

You can't use a gel coat for the interior? I thought you'd want interior surfaces that don't get covered to be smooth.

[@LifeOnTheHulls]

All margins between modules and hull and deck,gel coated then spray flow coated ,sanded and polished wet and dry to 1200 grit before buffing.Bit of work, but easily doable.Ross.

[@dc1544]

iTECH200 it says 250 amp discharge or 1.25C. IT will not let your inverter go over 3000 watts. inverters even 3kw ones can spike to 5kw with loads and that will not be possible how your batteries are hooked up now (parallel aka Daisy chain). Connecting each battery to a busbar would allow spikes up to 12 kw even though your inverter would never allow that. I just want to help do it correctly.

[@LifeOnTheHulls]

Batteries are connected through the lynx distribution bus bar 1000amp shunt prior to inverter as per victrons instructions with 4/0 Awg cable.

[@dc1544]

Running your 12 volt batteries in parallel (daisy chain) means the whole load goes through every battery. Causes more heat loss and higher C rating and lowers your cycle count life. If you connect each one to a busbar then it would mean each battery would take 25% of the load which causes less heat and will extend your cycle life a lot. Many manufacturers do this so you will buy batteries sooner so they will make more money. That is not the correct way. if you use 5000 watts from your inverter that is 417 amps that is over 2C rating. if you connect those 4 to a busbar each would be using .5C roughly. Lithium in lifepo4 cells break down from heat and high loads much faster. I did a ton of research on this before I setup my home battery system for solar and off grid use.

[@LifeOnTheHulls]

Batteries are linked to 1000amp busbars prior to inverter.All loads pass through this system prior to inverter and dc distribution.I followed rhe vixtron set up guide implicitly. Interesting to see that point though.Ross

[@dc1544]

@@LifeOnTheHulls good you changed it.

[@dc1544]

@@LifeOnTheHulls That still does not change how many amps your batteries can put out in parallel. you are jumping each battery together then to your Victron busbar. each battery needs to be connected separately to that busbar.

[@markdignam7470]

not sure you fitted the gasket on the second (silver) riser

[@LifeOnTheHulls]

Definately did mate.Good to have you checking me though.Ross

[@timdwyer4229]

Ross, you should have said the risers were for your Yanmar garden tractor. 50.00 each then!

[@LifeOnTheHulls]

Definately,such a disparity between marine and commercial.

[@aserta]

@@LifeOnTheHulls The disparity is them being greedy. Based on some pretty heavy economics voices, people who have been in the trade for half a century, some even more, the recent events and greedonomics might just break the camel's back. Either we come out of this worse, or better... hopefully, and one area that needs some verge trimming is marine. The prices they practice are absurd. I do home restorations, sometimes we have castings that far outtake that riser from both a material and complexity stand point and they never reach that kind of a price even when you consider the far lower number of items. In the middle of the lockouts, we were still working out little details on a 1700's house for a client. We had a run ordered of 400 or so intricate brass pieces and proportionally, it makes that rise seem like it's made out of pure silver. It's just absurd. A few years back, we had to replace an entire chandelier that had been too damaged and modified to be usable anymore. Details, lines, components, 860 euros all in all, for 30 lights and about ~25 kgs. So... a custom ordered item, one of a kind, with motifs galore and details... is cheaper than a computerized production run item? I dislike these kinds of people, like the plague.
